Title: Air-fuel ratio control device/for internal combustion engine with egr device
Inventor: YOSHIMURA SEIJI
IPC: F02D41/02
Filed: 1994-10-17
Abstract: PURPOSE: To suppress the generation of NOX under a condition that NO is increased and to suppress the increase of CO and HC under a condition that NOX is not increased by providing an air-fuel ratio control means to control an air-fuel ratio to the rich side with the decrease of an outside air pressure. CONSTITUTION: In an ECU 51, based on detecting signals from sensors 32, 33, 35, and 36, the values of an intake air amount, an intake air temperature, a water temperature, and the number of revolutions of an engine are read, and based on the values of an intake air amount and the number of revolutions of an engine, a fundamental injection amount is calculated. Further, by multiplying each correction parameter, a target injection amount is calculated and all conditions of a water temperature being increased to a value higher than a given temperature, the number of revolutions of an engine being below a given value, and a non-idle state state (an atmospheric pressure - an intake air pressure) being below a given pressure are satisfied after a lapse of a given time and more than stating from starting, an EGR valve 23 is closed.  In this case, a value determined by calculating a rich skip raising amount is added to a preceding rich skip amount to produce a new rich skip amount, which is added to a preceding air-fuel ratio correction value and the additional value is set as a new air-fuel ratio correction value.

Inventor: TOYODA HIDEO
IPC: G02B7/28
Filed: 1983-12-29
Abstract: PURPOSE:To improve rapidly the response speed while keeping the stability of system by decreasing the loop gain of the system when a focus matching passes by a position to be focused. CONSTITUTION:When a video camera and an object are moved, an output difference between the output of a detection circuit 13 and the output of a hold circuit 14 appears, an output of a comparator 15 is changed, and a control circuit 16 catches the change and controls a gain control circuit 17 so as to increase the loop gain. The loop gain is increased while the focus is matched and a motor 12 is driven in a fast response in the focusing direction. As soon as the focus matching device passes by the focusing position, the loop gain is decreased and even when the motor passesover the focus point due to inertia of the motor 12, the motor is made stable at the focus point without causing any hunting.
